I bought a used 400EX . When i bouth it i was told it has a 426 kit and a top end cam. well i tore it apart to replace the head gasket and wanted to look at the cam. I know it is a white bros. It has WB 1870 4-03 engraved into to cam. Can anyone tell me if this is the track cam or the all around cam, or is it a special grind.
